Attentional blink as a product of attentional control signals: A computational investigation

Abstract

Although there are several different hypotheses regarding the origin of attentional blink, including interference, inhibition, and attentional capacity based explanations, largely, there have been few attempts to cohesively understand attentional blink from a single unified visual-attentive processing model. In the current work we have chosen Cognitive Programs model of visual processing (Tsotsos et al, 2014) in order to illustrate how attentional blink arises from executive control signals of visual-attentive module and visual working memory module. We have computationally simulated the rapid serial visual presentation (RSVP) tasks detailed in Raymond et al. (1992) using letters and oriented bars in order to capture important features of attentional blink. The novel aspect of our work is that in our work attentional blink arises as a by-product of visual processing and attentive control other than less parsimonious accounts of attentional blink.
